Cambodia's Techo International Airport officially opened on September 9, 2025, marking a new milestone in the country's aviation development. Located in Kandal Province, about 19 kilometers from downtown Phnom Penh, the airport spans roughly 2,600 hectares.

The project was invested by Cambodia Airport Investment Co., Ltd. and constructed by China Construction Third Engineering Bureau Group Co., Ltd. (CCTEB). Work began in January 2020 and took more than five years to complete.

As the largest steel-structure project under construction in Cambodia in terms of volume and area, the airport features a steel-structured roof spanning 216 meters in width and 360 meters in length. Dome components weighing more than 11,000 tonnes, highlights the use of advanced construction techniques.

The project also emphasizes environmental sustainability. The airport's new energy center houses Cambodia's largest-capacity chiller system, while more than 1,000 solar panels have been installed, generating up to 120 million kWh annually and cutting carbon emissions by about 100,000 tonnes per year.

The opening of Techo International Airport is expected to ease pressure on Cambodia's existing airports, strengthen the country's air transport capacity, and inject fresh momentum for tourism and economic growth.
